controller - 2 render templates (from devise) on one page (rails 3) -

i've installed devise rails app, can go sign in page or sign page. want them both on welcome page...

so i've made welcome_page_controller.rb following function:

    class welcomepagecontroller < applicationcontroller   def index     render :template => '/devise/sessions/new'     render :template => '/devise/registration/new'    end end 

but when go welcome page error:

nameerror in welcome_page#index  showing /users/tboeree/dropbox/rails_projects/rebasev4/app/views/devise/sessions/new.html.erb line #5 raised:  undefined local variable or method `resource' #<#<class:0x104931c>:0x102749c> extracted source (around line #5):  2: <% @header_title = "login" %> 3:  4:  5: <%= form_for(resource, :as => resource_name, :url => session_path(resource_name)) |f| %> 6:   <p><%= f.label :email %><br /> 7:   <%= f.email_field :email %></p> 8:  

does knows solution problem? in advance!

does have fact missing resource function? in welcome_page controller? it's somewhere in devise controller...?

regards, thijs

here's how managed did it.

i've put sign form in home#index

my files:

view/home/index.html.erb

<%= render :file => 'registrations/new' %> 

helper/home_helper.rb

module homehelper   def resource_name     :user   end    def resource     @resource = session[:subscription] || user.new   end    def devise_mapping     @devise_mapping ||= devise.mappings[:user]   end    def devise_error_messages!     return "" if resource.errors.empty?      messages = resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join     sentence = i18n.t("errors.messages.not_saved",                       :count => resource.errors.count,                       :resource => resource_name)      html = <<-html <div id="error_explanation"> <h2>#{sentence}</h2> <ul>#{messages}</ul> </div> html      html.html_safe   end  end 

you need part because devise works called resource , should defined can call registration#new anywhere.

like that, should able register. however, needed display errors on same page. here's added:

layout/home.html.erb (the layout used index view)

<% flash.each |name, msg| %>    # new code (allow flash elements arrays)   <% if msg.class == array %>     <% msg.each |message| %>       <%= content_tag :div, message, :id => "flash_#{name}" %>     <% end %>   <% else %>      # old code     <%= content_tag :div, msg, :id => "flash_#{name}" %>    <% end %> #don't forget end <% end %> 

i found code here

and here's created: saved resource object if invalid in session user hasn't fill every field again. guess better solution exists works , it's enough me ;)

controller/registration_controller.rb

def create     build_resource      if resource.save       if resource.active_for_authentication?         # delete session created incomplete subscription if exists.         if !session[:subscription].nil?           session[:subscription] = nil         end          set_flash_message :notice, :signed_up if is_navigational_format?         sign_in(resource_name, resource)         respond_with resource, :location => redirect_location(resource_name, resource)       else         set_flash_message :notice, :inactive_signed_up, :reason => resource.inactive_message.to_s if is_navigational_format?         expire_session_data_after_sign_in!         respond_with resource, :location => after_inactive_sign_up_path_for(resource)       end     else       clean_up_passwords(resource)       # solution displaying devise errors on homepage found on:       # https://stackoverflow.com/questions/4101641/rails-devise-handling-devise-error-messages       flash[:notice] = flash[:notice].to_a.concat resource.errors.full_messages       # store invalid object in session user hasn't fill every fields again.       # session deleted if subscription becomes valid.       session[:subscription] = resource       redirect_to root_path #set path want here     end   end 

i think didn't forget code. feel free use whatever need.

also, can add sign in form in same page (something that:)

<%= form_for("user", :url => user_session_path) |f| %>     <%= f.text_field :email %>         <%= f.password_field :password %>   <%= f.submit 'sign in' %>   <%= f.check_box :remember_me %>   <%= f.label :remember_me %>   <%= link_to "forgot password?", new_password_path('user') %> <% end %> 

cheers !
